Beam Propagation Factor of Anomalous Hollow Beams in Oceanic Turbulence
Based on the extended Huygens-Fresnel principle and Wigner distribution function, the formulas for the propagation factor of anomalous hollow beams in oceanic turbulence are derived and the corresponding numerical calculation and analysis are carried out. The results indicate that the propagation factor of anomalous hollow beams will reduce along the decrease of the transmission distance and the increase of beam wavelength; when the transmission distance is fixed,the propagation factor of anomalous hollow beams will reduce at first, then increase with the increase of beam width; and the beams also reduce at first, and it is invariant in the end with the coherence length increased on the same premise. In oceanic turbulence, the propagation factor of anomalous hollow beams is associated with the kinetic energy dissipation rate, the temperature variance dissipation rate, and the salinity and temperature change ratio. The propagation factor must reduce gradually due to the increase of kinetic energy dissipation rate and the increase of the temperature variance dissipation rate and the salinity and temperature change ratio. These results are useful for the transmission and application of beams in the oceanic turbulence.
